A cashew drying machine is industrial batch drying equipment that removes moisture from shelled cashew kernels through controlled hot-air circulation. The machine featured on this page is Shuliy’s drying room for cashew processing, a sealed box-type dryer built from stainless steel. It processes 300 to 8,000 kg of cashew kernels per batch, depending on the model, and lowers kernel moisture to a stable level for shelling, storage, and export.
Compared with sun drying, this cashew nut dryer delivers uniform temperature, adjustable humidity, and all-weather operation. It prevents mold, discoloration, and flavor loss while making cashew shells brittle enough for clean cracking. For processors building or expanding a cashew line, it offers a cost-effective way to improve kernel yield and product value.
Shuliy has supplied food drying equipment to buyers in over 30 countries for more than 20 years. Each machine is backed by installation support, operator training, and a one-year warranty with lifetime technical assistance.
Why Cashew Processors Need a Dryer?
Caroços de caju recém-descascados contêm alta humidade. Se não forem secos de forma adequada e atempada, podem levar a:
- Crescimento de mofo e contaminação bacteriana
- Cor escurecida e sabor inferior
- Prazo de validade reduzido
- Absorção de humidade e deterioração do sabor
- Dificuldade na remoção da casca
O uso de equipamento de secagem profissional garante que cada lote de cajus atinja o nível de humidade adequado, garantindo sabor e aparência consistentes.

Key Features of OurCashew Drying Machine
Sealed Stainless Steel Chamber
The chamber and trays use corrosion-resistant 304 stainless steel. This protects kernels from contamination, meets export food-hygiene requirements, and allows fast cleaning between batches.
Precise Temperature & Humidity Control
A PLC controller manages drying temperature, airflow, and cycle time automatically. Operators set the curve once and the machine maintains stable conditions throughout the batch.
Forced Hot-Air Circulation
High-power circulating fans distribute heated air evenly across every tray layer. Top, middle, and bottom trays dry at the same rate, reducing rework and tray rotation.
Flexible Heat Sources
Choose air-source heat pump, electric heating, sulfur-free coal, or hybrid energy. Heat-pump operation typically cuts energy use by 30–50% compared with pure electric heating.
Modular Capacity
Units from SL-2 to SL-24 share the same core design. Start with a small industrial cashew dryer and expand later, or choose a larger model for full commercial output.
Compact Footprint & Quick Installation
The box-type structure needs no complex civil works. Most models arrive pre-assembled and can be installed and commissioned within one to two days.
How the Cashew Drying Machine Works?
- Loading: Spread shelled cashew kernels evenly on stainless steel trays. Do not overload; airflow must reach every layer.
- Heating: The heat source warms air inside the sealed chamber.
- Circulation: Circulating fans push hot air through the trays. Moisture evaporates from the kernels.
- Dehumidification: A humidity-controlled exhaust fan removes moist air while fresh dry air enters.
- Cooling & Unloading: Once moisture reaches the target level, kernels cool inside the chamber before shelling or packaging.
Typical drying conditions for cashew kernels: 50–65°C air temperature, controlled humidity, and 6–14 hours per batch, depending on initial moisture and target level.
Cashew Processor Pain Points & Solutions
| Pain Point | Solução Shuliy | Result |
|---|---|---|
| Kernels mold before processing | Fast batch drying in sealed chamber | Longer safe storage |
| Uneven color and taste | PLC temperature and humidity control | Consistent product quality |
| High shelling breakage | Controlled moisture reduction makes shells brittle | Higher whole-kernel yield |
| High electricity bills | Air-source heat pump option | 30–50% energy savings |
| Weather-dependent production | All-weather indoor drying | Predictable output year-round |
Drying Room vs Mesh Belt Cashew Drying Machine
For most cashew processing plants, the box-type drying room is the right choice. It offers lower investment, simple operation, and flexible batch sizes.
For very large-scale continuous lines that run 24 hours a day, a mesh belt dryer may be worth considering. This continuous conveyor dryer feeds and discharges automatically and handles several tons per hour. You can read more about it on our continuous conveyor dryer page.

| Production mode | Batch | Continuous |
| Best capacity range | 300–8,000 kg/batch | 400–14,000 kg/h |
| Initial investment | Lower | Higher |
| Operation | Simple | More automated |
| Ideal for | Small to large cashew plants | Very large continuous plants |
Por que usar uma máquina de secar cajus?
Faster Drying, Higher Production Efficiency
A circulação de ar quente acelera a evaporação da humidade, reduzindo significativamente o ciclo de secagem e facilitando o aumento da produção. Ideal para fábricas de médio a grande porte.
Even Drying for More Stable Product Quality
O controlo preciso de temperatura e humidade evita a sobresecagem, subsecagem ou descoloração, garantindo uma cor e sabor consistentes dos cajus.
Easier Shelling, Higher Kernel Yield
Casca de cajus seca torna-se mais quebradiça e o conteúdo de humidade diminui uniformemente, facilitando a casca, reduzindo quebras e melhorando o rendimento do caroço inteiro.
Unaffected by Weather, Year-Round Processing
A qualidade de secagem consistente é garantida independentemente de estações chuvosas, húmidas ou quentes, tornando o planeamento da fábrica mais previsível.
Ensures Food Hygiene, Suitable for Export
Um ambiente de secagem fechado evita contaminação por poeira e insetos. A construção em aço inoxidável reforça ainda mais a segurança alimentar.
Reduces Labor Costs, Improves Automation
Minimiza operações manuais como virar, mover ou secar ao sol, economizando mão-de-obra e evitando inconsistências de qualidade causadas por fatores humanos.
Energy-Saving Design, Lower Operating Costs
Boa isolamento e circulação de ar quente melhoram a utilização do calor, reduzindo o consumo de energia enquanto mantêm a eficiência.
Extends Shelf Life and Market Competitiveness
O conteúdo de humidade estabilizado após a secagem previne mofo e deterioração, garantindo armazenamento e transporte mais seguros, além de aumentar a competitividade no mercado.
